A doll system simulates weight gain and weight loss in a doll by the selective expansion and contraction of parts of the doll subject to simulated weight gain and weight loss by selectively coupling a chamber within the doll with a pressure-raising apparatus configured to simulate a weight gain object or a pressure-lowering apparatus configured to simulate a weight loss object and operating the coupled apparatus to either raise the pressure within the chamber to simulate weight gain or lower the pressure within the chamber to simulate weight loss.
